Abstract (en)
[origin: EP3611066A1] A brake cylinder device (60) includes the spring brake (80), a ring (101, 201) for coupling a transmission member (84) to a second piston (82), the transmission member (84) being configured to transmit a force to the spring brake (80), and a switching member (102, 202) configured to rotate to disengage from the ring (101, 201) so as to switch a braking force of the spring brake (80) to a non-transmission state.
